35 -Of these four points, the last two will be discussed in separate microlearnings. In this microlearning, we will focus on the first two aspects of the configuration. As you might have noticed I did not mention the fact whether the integration is synchronous or asynchronous as a crucial part of the configuration. The reason being that when configuring a (SOAP) web service you always need to send an acknowledgment back to the client calling the web service to let them know what the status of the message is. In case you want to set up the rest of your integration asynchronously you can send an empty message back as acknowledgment. In case you want to set up the rest of your integration synchronously you need to send the response you have received from the backend operation back to the client. More on the choice between asynchronous and synchronous in a later stage.
32 +Of these four points, we will zoom in on the validation part of our SOAP Webservice in this microlearning. The SOAP Webservice serves as a point of entry where people with the proper credentials (security) and the correct answers (validation) can enter and perform their actions. In the previous microlearning, we talked about the security part. In this microlearning, we talk about the validation part.

37 -=== 3.1 Operation Name ===
34 +=== 3.1 Configuration on system message level in Design ===
38 38  
39 -Let us first zoom in on the parts of the configuration before we learn how you can implement it in eMagiz. Starting with the operation name. When you have dealt with the API Gateway offering of eMagiz in the past or have some knowledge of how APIs work the notion of an operation name should not be unfamiliar. In essence, it is a unique name that defines a certain operation. In eMagiz the best practice for naming the operation is as follows:
36 +As you have learned from the crash course, you can validate an XML message with the help of an XSD. This XSD describes data types, order, associations, and length of attributes. You can use such an XSD to validate what your clients send you. eMagiz will automatically define a WSDL based on the combination of system messages you provide for each operation you want to host. To ensure that the WSDL is created correctly, don't forget to add an entity called "Send{givenname}Request" to the (request) system message and an entity called "Send{givenname}Response" in case you have a response system message. An example of how this needs to be configured in Design is shown below.
40 40  
41 -* Send{technicalnameoftheoperation}
38 +[[image:Main.Images.Microlearning.WebHome@novice-soap-webservice-connectivity-validate-incoming-messages-gen3--root-entity-for-wsdl.png]]
42 42  
43 -When you are in Create you will notice that eMagiz uses the default suffix of Request and Response is added to the operation name. Therefore the full operation name a client needs to call to get the desired result if you adhere to the best practice is:
40 +=== 3.2 Effect in Create ===
44 44  
45 -* Send{technicalnameoftheoperation}Request
42 +In the infra flow, eMagiz automatically adds a support object of the "Dynamic WSDL" type. In this support object, the link is made between the system message definitions and the WSDL that will be created based on this.
46 46  
47 -=== 3.2 SOAP Webservice Namespace ===
44 +[[image:Main.Images.Microlearning.WebHome@novice-soap-webservice-connectivity-validate-incoming-messages-gen3--dynamic-wsdl-support-object-infra.png]]
48 48  
49 -The second part of the configuration is the SOAP Webservice Namespace. When hosting a SOAP Webservice via the standard eMagiz tooling you need to define a namespace. To smoothen this process eMagiz automatically generates a namespace based on the configuration settings you choose in the Design phase of eMagiz.
46 +{{warning}}Note that when you make changes to the system message after the integration is already in Create, or when you add a new integration to Create, you need to create a new version of your infra flow to be able to deploy the changes to your WSDL.{{/warning}}
50 50  
51 -=== 3.3 Configuration in eMagiz ===
48 +In this same support object, you also see the default location of the hosted SOAP endpoint, which is http://localhost:${entry.connector.ws.port}/ws/{soap WS name}/. Based on this, you can find the WSDL by adding {soap WS name}.wsdl to the URI. In this example, when hosting the SOAP web service on-premise, a valid URI would be "http://localhost:8099/ws/soapgn3-connector/soapgn3-connector.wsdl".
52 52  
53 -Now that we know what configurations are required, we can see how we can implement this in eMagiz. In the Capture phase, nothing changes. You simply draw a system on the canvas including at least one line that goes from the system towards eMagiz. When you are done you move to the Design phase in eMagiz. In this phase, you need to correctly set up the operation name(s) and the SOAP Webservice Namespace.
50 +{{info}}Note that when running your web service in the eMagiz cloud, the first part (the host part) will change depending on your configuration in Deploy Architecture and the cloud slot on which you are running. An example URI, in that case, would be "https://soap-test-cloud0000.emagizcloud.com/ws/soapgn3-connector/soapgn3-connector.wsdl"{{/info}}
54 54  
55 -The configuration in Design starts at the system level. At the system level, you need to define the technical name (or let eMagiz automatically fill it in for you) and select the checkbox called Combined Entry Connector. By selecting this checkbox you tell eMagiz that you want to host an endpoint for others to call.
52 +With this done, you have successfully added validation to your SOAP web service.

67 -With this, you are done with your configuration on the system level. Don't forget to update the status of your task. Now that we have configured the system it is time to configure the integration that is drawn from the system to eMagiz. We can do so by double-clicking on it (or by accessing the context menu and selecting the edit option). When you open the Edit page on the integration level you will notice that a new segment is added (compared to other integrations). This segment defines the settings on the system level we have just specified and defines the operation name.

71 -As you can see eMagiz has already prefilled the operation name for you based on the best practice at eMagiz. If you want to change you have the option to do so. Do note that for the sake of consistency it would be smart to use the same naming convention within a single project to avoid confusion.

73 -=== 3.4 Add integration to Create ===

75 -Now that we have finished the configuration in Design the last step of this microlearning is to add the integration to Create. You can simply do so by navigating to Create -> Add integrations and selecting the integration to move it to Create. After you have selected it press Save to add the integration to Create.
